A nurse is mixing regular insulin and NPH insulin in the same syringe prior to administering it to a client who has diabetes mellitus.
Which of the following actions should the nurse take first?
Inject air into the NPH vial.
Withdraw the NPH insulin from the vial.
Withdraw the regular insulin from the vial.
Inject air into the regular insulin vial.
The Correct Answer is A
The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:
-
Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
-
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
-
Withdraw the regular insulin from the vial : The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
-
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.
This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

Correct Answer is A
Explanation
The client should stay upright for at least 15 minutes after taking ferrous gluconate to prevent oesophagal irritation. Choice B is wrong because taking an antacid with ferrous gluconate can decrease its absorption and effectiveness.
Choice C is wrong because taking ferrous gluconate with milk can also reduce its absorption and cause gastrointestinal distress.
Choice D is wrong because black stools are a common and harmless side effect of ferrous gluconate and do not indicate a need to notify the provider. Ferrous gluconate is an iron supplement used to treat or prevent iron deficiency anaemia, a condition where the body does not have enough red blood cells to carry oxygen to the tissues.
Iron is an essential component of haemoglobin, the protein that carries oxygen in the blood.
Correct Answer is B
Explanation
This is the recommended dosage for cyanocobalamin nasal spray for pernicious anaemia and vitamin B12 deficiency. Cyanocobalamin nasal gel is used to prevent a lack of vitamin B12 that may be caused by various factors.
Choice A is wrong because the duration of treatment depends on the individual’s response and blood levels of vitaminB. Some people may need to use this medication for longer than 6 months.
Choice C is wrong because there is no need to lie down for 1 hour after administering the medication.
This may cause nasal irritation or drainage.
Choice D is wrong because using a nasal decongestant 15 minutes before the medication may interfere with the absorption of cyanocobalamin. If you have a stuffy nose, you should talk to your doctor about alternative ways to take vitaminB.
